BMW's Alpina plans, a five-star roadster, Prior's Morgan

The Mazda MX-5 is a lightweight, front-engine, rear-wheel-drive roadster known for delivering a fun, balanced driving feel. In this segment, they’re discussing how the MX-5 has been updated over time—engine “tweakery,” improved throttle control, and a better differential—so it can still score highly even after many years on sale.

“Diff” is short for differential, the drivetrain component that allows the left and right wheels to rotate at different speeds while turning. When they say it’s “a better diff,” they’re implying an update that improves traction and how the car behaves under load.

A land-speed record is an attempt to achieve the highest speed possible by a vehicle on land, typically measured over a defined course and conditions. This segment references JCB’s record-style efforts at Bonneville, where Andy Green drives specialized machines to extreme speeds.

JCB is a company known for construction equipment like diggers, and in this segment it’s also pursuing extreme-speed experiments. The host says JCB shifted from a diesel-based record concept to hydrogen-powered digger engines for a new Bonneville attempt.

Hydrogen burning piston engines are internal-combustion engines that use hydrogen as the fuel instead of gasoline or diesel. The idea is to keep the familiar piston-engine hardware while switching the energy source, which can make integration into existing vehicle designs easier than using hydrogen fuel cells.

Brake horsepower (bhp) is a measure of an engine’s power measured at the crankshaft using a dynamometer. It’s a common way UK/European sources report power, and it’s different from wheel horsepower because it doesn’t account for drivetrain losses.

A space frame is a rigid vehicle structure made from a network of tubes or members that triangulate loads. It’s often used in race cars and record cars because it can be very strong while keeping weight down.

A carbon cell refers to a driver safety compartment (often a monocoque-like survival cell) built from carbon fiber. Carbon fiber is strong and light, and the cell is designed to protect the driver in high-energy impacts.

Bonneville typically refers to the Bonneville Salt Flats in Utah, famous for land-speed records. Vehicles are engineered specifically for straight-line stability, traction, and aerodynamic efficiency over long salt-flat runs.

Traction control is a driver-assistance system that reduces wheel spin when the tires lose grip. It typically does this by cutting engine power and/or applying brakes to the slipping wheel(s).

Stability control (often called ESC) helps prevent skids by detecting loss of steering control. When the car is sliding or rotating too much, it selectively brakes individual wheels and may reduce engine power to bring the vehicle back in line.

Anti-roll control is an active chassis system designed to reduce body roll during cornering. Instead of relying only on passive anti-roll bars, it can use braking and/or suspension control to keep the car flatter and more stable.

Roll mitigation refers to safety logic that intervenes to reduce the risk of excessive body roll or even rollover. In practice, it may limit how much the car can lean by using braking, torque reduction, and/or suspension control.

The Aston Martin DBX is a high-performance luxury SUV from Aston Martin, combining everyday practicality with sports-car-style performance. It’s a notable model because it brings Aston Martin’s brand identity into the SUV segment. The podcast mentions it in connection with cornering shots, highlighting its on-road dynamics.

A roof rack and roof box change the vehicle’s aerodynamics and center-of-gravity, which can affect how chassis control systems behave. The host suggests the DBX’s roll-mitigation calibration may have been set up for that added load, changing how easily it will slide.

Four-wheel drive (4WD) sends power to all four wheels to improve traction. The host notes the DBX is rear-biased but can shift power forward when conditions get “hairy,” which is typical of electronically controlled AWD systems.

The Fiat 130 Coupe is a classic Italian grand-touring coupe known for its clean, chiseled Pininfarina-style design language. In this segment, it’s discussed as a rare, desirable car that even designers who haven’t seen it before get excited about.

Pininfarina is an Italian design house best known for shaping the look of many iconic cars. In this segment, it’s used to explain that the Fiat 130 Coupe’s bodywork and “clean, chiseled” styling were designed for Pininfarina by an Italian designer.

The Fiat 130 3200 Coupe is a classic Italian grand tourer built around a larger-displacement engine and a comfortable, long-distance focus. It’s the kind of car that tends to attract attention because it’s rarer and more distinctive than many mainstream classics. The podcast mentions searching auction houses for one, which signals its collectible status.

The Fiat 132 Coupe is referenced as another example of a Fiat coupe that the hosts’ designer, Ben Someril, hadn’t encountered before. It’s used to reinforce that the Fiat 130 Coupe’s design and engineering ideas feel familiar to people who think like designers.

A “3.2 litre quad cam V6” describes an engine with six cylinders (V6) and four camshafts total (quad cam), displacing 3.2 liters. Quad-cam setups typically allow more precise control of valve timing, which can improve how the engine breathes across the rev range.

“Ferrari Dino” refers to Ferrari’s Dino-branded engines, which are famous for their high-performance engineering and racing heritage. The host is suggesting the Fiat 130 Coupe’s V6 is related to that Dino engine family, which would be a big deal for enthusiasts because it implies serious pedigree.

The Fiat Dino Coupe is a classic sports car associated with the Dino name, known for its compact, performance-focused design. It’s often discussed in relation to the Dino engine family and how the Dino models fit into the broader history of Italian sports cars. The podcast asks whether it came before or around the same time as the later Dino 208 GT4/Spyder discussion.

The Ford Granada is a mid-size car that was sold in multiple markets and is remembered as a comfortable, traditional family/commuter model. It’s mentioned in the podcast as a reference point for the look or “shades” of another car—specifically the Fiat 130—suggesting a similar design vibe. That kind of comparison is common when discussing classic styling.

“Brutalist architecture” is a design style associated with raw, blocky forms and minimal curves. The host uses it as a metaphor for the Fiat 130’s styling—arguing that the car’s sharp, angular proportions can make people dismiss it at first, until they learn to “see the point.”

BMW Alpina refers to Alpina’s cars built on BMW platforms, where Alpina is known for tuning and refining BMW drivetrains and chassis for a more distinctive, luxury-performance character. The host says Alpina has launched a concept car and is presenting it at a major Italian event.

Villa d’Este is a famous luxury car concours event in Italy, where collectors and manufacturers showcase notable vehicles. In this segment it’s mentioned as the setting for Alpina’s concept-car launch.

“Bespoke” means the car is tailored specifically for that brand or customer rather than being a standard, widely shared model. Here, the hosts use it to say the concept is unique to Alpina and not simply a BMW variant.

The segment explains Alpina’s history: it was an independent brand run by the Bovenseepen family, producing cars based on BMW platforms. This background matters because it clarifies why Alpina’s identity is distinct from BMW’s own lineup.

The hosts describe how BMW acquired Alpina’s brand after the Bovenseepen family found it too complicated to keep operating. This acquisition is relevant to understanding how Alpina can remain a distinct tuner while being tied to BMW.

An “electric” car uses an electric motor powered by a battery, rather than relying on a combustion engine. The hosts are weighing whether an all-electric version would be commercially viable if customers don’t want it.

A plug-in hybrid (PHEV) is a car that combines a conventional engine with an electric motor and a battery that can be charged from an external power source. The hosts discuss it as a potential product direction, but question whether enough customers would want it.

“Bovenseepen Zegato” refers to a coach-built car project using the Zegato name, which is associated with bespoke, low-volume coachbuilding. In the segment, it’s described as a new launch that will be built in smaller numbers and at higher cost than before.

The Alpina B6 is a BMW-based performance sedan/fast grand tourer from Alpina, a tuner that builds cars with its own engine tuning and chassis calibration. In this episode, the hosts say BMW specifically admired the B6 as the model that best embodied Alpina’s brand identity.

The BMW 7 Series is BMW’s flagship luxury sedan line, typically associated with large size, comfort, and high-end powertrains. The hosts say BMW expected the first Alpinas to be “seven series sized,” meaning Alpina’s initial offerings would target the biggest, most premium segment rather than starting with smaller models.

The BMW M3 is BMW’s performance “M” model, known for a more aggressive, track-capable character than standard 3 Series cars. In this segment, the hosts say the M3 is already quite aggressive, implying BMW’s M lineup is already pushing the envelope.

The BMW M5 is BMW’s high-performance version of the 5 Series, typically blending strong acceleration with a more usable, “big car” daily-driver feel. Here, the hosts suggest the M5 may not be aggressive enough yet compared with what an Alpina 5 Series could offer, and they discuss how BMW could make future M cars more aggressive.

The Haggerty Hill climb is a motorsport event format where cars race against the clock up a steep course. In this segment, the host uses it to describe the kind of cars that show up and the vibe of the event.

Shelsley Walsh is a famous UK hill-climb venue known for its challenging course and long history in motorsport. The host mentions running up there to give listeners a sense of the event’s character and the types of cars present.

The Toyota Prius is a hybrid car that became one of the most recognizable choices for fuel-efficient everyday driving. It’s often discussed because it helped popularize hybrid technology for mainstream buyers. In the podcast context, it’s mentioned in relation to how many people actually have them versus expectations.

A steering committee is a group of decision-makers that sets direction and approves major choices. In this context, it’s being used as a humorous stand-in for internal stakeholders deciding between petrol and electric options based on practical constraints like range.

Range is how far a vehicle can travel before it needs refueling or recharging. For electric cars, range limits can affect whether you can complete a trip without stopping to charge, which is why the host mentions the steering committee not wanting to be constrained by it.

A three-wheeled vehicle uses one wheel at the front and two at the rear (or vice versa), which changes how it steers and how it feels compared with a typical four-wheel car. It also affects stability and packaging, which is why three-wheelers are often built as lightweight, simple runabouts.

A three-wheeler is a vehicle with one wheel at the front or rear and two wheels on the other end, creating a distinctive driving feel compared with four-wheel cars. In the podcast, it’s referenced as part of a column studying Morgan three-wheelers, which are known for their unusual layout and lightweight, open-road character. The mention about rain and whether it’s “just” starting to rain points to how weather affects traction and handling.

Brooklands was a famous British motor-racing circuit and test venue, historically associated with early speed trials and record attempts. Mentioning it signals the car’s performance testing heritage rather than normal road use.

Morgan is known for its three-wheeled roadsters, which use a narrow, motorcycle-style front end with two wheels in front and one wheel at the rear. In this segment, the host discusses Morgan keeping a three-wheeler in production through the early 1950s and later reintroducing new three-wheeler designs.

Morgan Super 3 is a modern take on the brand’s three-wheeled roadster formula, positioned as an updated “clean sheet” design direction. The host says it’s one of the earliest Super Threes they had as a press demonstrator and highlights its look and early ownership/road-test context.

A tonneau is a cover—often a soft or folding top—that protects the passenger compartment and/or rear storage area when the car is open. The host notes the car has a tonneau over it, which helps explain why it’s usable even while raining.

A “Walker ramp” refers to a specific ramp used at the Morgan factory for demonstration/vehicle handling during road-test or display setups. In this context, the host mentions using it as part of getting the press demonstrator ready to drive.

The Renault 5 is a compact hatchback that became well known for its practicality and long-running popularity. It’s often referenced in car conversations because it has a strong place in classic European motoring history. In the podcast, it’s mentioned alongside the Twingo as something the host likes to look at.

The Renault Twingo is a small city car designed for easy maneuvering and parking in tight urban spaces. It’s frequently mentioned because it’s a practical, compact alternative in the small-car category. In the podcast, it comes up via a listener note and alongside discussion of the Renault 5.

Hill climbing is a motorsport where cars race against the clock on an uphill course, often with tight turns and varying grip. Builds for hill climbing tend to prioritize responsive handling, traction, and a powerband that works well at the speeds you’ll see on the climb.

A hot hatch is a compact hatchback tuned for stronger acceleration and sharper driving dynamics than a normal family hatch. The term usually implies a sportier engine tune, suspension/brake upgrades, and a big aftermarket scene for modifications.

The Peugeot 205 GTI is a classic hot hatch from Peugeot, famous for its lightweight feel and responsive handling. In enthusiast circles it’s also known for being relatively easy to modify, which is why it shows up in discussions about budget builds and track-style driving.

The Volkswagen Golf is a mainstream compact hatchback known for being practical, efficient, and widely available in many generations. It often comes up in car discussions because it’s a common reference point for everyday driving and for how manufacturers evolve their “everyday” models over time. In the podcast context, it’s mentioned alongside another popular choice as a typical car people might have considered.

The Peugeot 205 CTI is a performance-oriented variant of the Peugeot 205, a popular compact from the 1980s and early 1990s. It’s significant because it offered a more spirited driving experience than the basic models, which helped it build a strong enthusiast following. The podcast references it as part of a route that leads to the Peugeot 205 GTI being completed and ready.

The Porsche Macan EV is Porsche’s electric version of the Macan, moving the brand’s compact-SUV formula to battery power. The segment uses it as an example of how modern infotainment/voice systems behave in real life.

The BYD C-Lion 7 is an electric vehicle from BYD, used here as a contrasting example to the Porsche’s voice-command response. The point is less about performance and more about how different brands’ in-car systems handle the same request.

Wind deflectors are small aerodynamic pieces mounted at the edge of side windows. They help channel airflow into the cabin while reducing wind noise and “buffeting” when the window is cracked open.

The Land Rover Defender is a rugged, off-road-focused SUV known for its boxy styling and long-running, utilitarian design. In this segment, it’s mentioned as the host’s car that has window wind deflectors for ventilation.

Buffeting is the vibration and turbulence you feel and hear when air flows around an opening—like a partially lowered window. It’s caused by unstable airflow that creates pressure fluctuations, which wind deflectors can reduce.

Thrust SSC is the supersonic land-speed-record car associated with Andy Green. It’s notable because it was designed to break into the sound barrier on wheels, using extreme aerodynamics and powerful jet propulsion.

Throttle control is how precisely a driver manages the accelerator pedal to meter engine power. In racing, small changes can strongly affect traction and balance, especially when the engine is turbocharged or when grip is inconsistent.

BHP stands for brake horsepower, a measure of an engine’s power output. It’s commonly used in automotive contexts to compare how much power an engine produces under test conditions.

A turbocharger (“turbo”) uses exhaust gas to spin a turbine that forces more air into the engine. That lets the engine make much more power than it would naturally aspirated, but it also makes throttle response and traction management more critical.

Feathering the throttle means making very small, smooth adjustments to the accelerator instead of abrupt on/off inputs. The goal is to keep the car balanced and the tires in the right traction range while still maintaining speed.

Using the rear brake strategically can shift weight rearward and help rotate the car into a turn. In performance driving, that can be part of a technique to induce oversteer/rotation when the front is heavily loaded or when the driver wants the car to pivot more readily.

The mention of “one for each rear wheel” points to independent rear braking control, where each rear wheel can be managed separately. That kind of control can help fine-tune rotation and stability because braking force can be distributed where it’s most effective.

The phrase describes a rotation-focused driving behavior: the car pivots around a chosen point/axis rather than simply arcing through the turn. Techniques like rear braking and high steering angles can encourage this kind of rotation, changing how the driver feels the car’s balance at turn-in.

“Lock” here refers to steering lock—how far the steering can be turned. The speaker is emphasizing that the car can achieve very large steering angles, which can increase how quickly the car can rotate, especially when paired with braking/traction techniques.

RPM (revolutions per minute) is how fast the engine crankshaft spins. Saying the car can go from 800 RPM at idle to much higher RPM describes how smoothly it can operate at very low engine speed and then accelerate through the rev range.

RPM (revolutions per minute) indicates engine speed, and higher RPM generally means the engine is producing more power (up to its designed limit). The mention of pulling all the way to 9,000 RPM emphasizes the engine’s usable rev range in this small trials car.

A trials car is built for trials-style driving, where the goal is to negotiate obstacles slowly and precisely rather than race for speed. That’s why the speaker talks about very low RPM control and then pulling through the rev range while maneuvering around tight, uneven terrain.

WSH here appears to be an acronym tied to the vehicle’s high-speed/jet-hydrofoil concept, but the transcript doesn’t define it. Because the meaning isn’t clear from the audio text alone, it’s worth flagging for listeners: it likely refers to a specific engineering system or performance mode used in the project.

A powertrain is the set of components that generate and deliver drive power—typically the engine plus the transmission and drivetrain elements. Here, the host says the builder used the “Imp powertrain” but rerouted it to drive the front wheels.

Front-wheel drive (FWD) means the engine sends power to the front wheels, which handle both propulsion and steering. In the segment, the host emphasizes how converting an “Imp” powertrain to FWD changes where the engine sits relative to the front axle and how the car packages its weight.

A supercharger is a forced-induction device that increases engine air intake pressure, allowing more fuel to be burned and typically producing more power. The speaker connects “supercharged” to the described hill-climb car’s front-wheel-drive conversion, implying it was tuned for extra shove.

Weight distribution describes how a car’s mass is spread front-to-rear (and sometimes side-to-side). The speaker claims the conversion produced “lovely” weight distribution, which matters because it affects balance, traction, and how the car behaves in corners—especially for a hill-climb style build.

A “three-speed box” refers to a transmission with three forward gear ratios. Older cars and many post-war specials often used simple multi-gear setups like this, which affects how the car accelerates and how it cruises at speed.

Drum brakes use brake shoes that press outward against a rotating drum to slow the vehicle. They were common on older cars, especially before disc brakes became widespread, and they tend to be less effective at repeated high-speed braking than modern disc setups.

Non-independent suspension means the left and right wheels are mechanically linked, so movement on one side affects the other. This can reduce ride comfort and grip consistency compared with independent suspension, but it can be simpler and robust on older or purpose-built cars.

The DRW Imp Sport Racer is a niche, custom-built racing-style car that’s being discussed as a “special” from the post-war era. In the segment, the host suggests it likely uses an Austin-Healey Imp engine and is configured as a mid-engine, rear-wheel-drive layout.

The Dodge Charger is a performance-focused sedan/coupe that’s known for its muscular styling and strong engine options. It’s significant historically because the Charger name has been used across multiple generations of American performance cars. The podcast reference to “a third generation wall charger” is likely a wordplay/connection to the Charger name rather than a discussion of the car’s charging technology.

A skidpan (skid pad) is a controlled surface used to safely demonstrate and practice loss-of-traction situations. Drivers can work on how tires and stability/traction systems behave when the car starts to slide, without risking public-road traffic.

Leapmotor is an automotive brand known for producing electric vehicles. Here, the host references a Leapmotor long-termer, meaning a long-term test car they’ve been living with to evaluate real-world behavior.

A traction button typically changes how the car’s traction control system intervenes. Traction control limits wheelspin during acceleration, and different settings can make the car either intervene more aggressively or allow more slip for a sportier feel.

A stability button usually adjusts the car’s electronic stability control (ESC), which helps keep the vehicle pointed in the direction the driver intends. Different modes can reduce intervention for more driver involvement or increase it for maximum assistance on slippery surfaces.

“Tires exploded” describes catastrophic tire failure under extreme heat and friction loads—common in long, sustained drifts. When tires overheat and degrade, they can fail suddenly, ending the run.

A “drift” is a driving technique where the car is steered while the rear end is intentionally sliding, usually to maintain control while keeping speed. “Longest drift” refers to staying in that controlled slide for the maximum distance or time—here, until the tires fail.

“Refueling” in this context is unusual: the car is still moving while fuel is added during the drift attempt. That turns the run into a combined endurance-and-control challenge, because the driver must keep the car stable while the fueling happens.

“Low grip surfaces” are road or track conditions where the tires don’t get much traction, making it easier for the car to slide. Drifting becomes more achievable because the driver can keep the car in a controlled slide rather than fighting sudden loss of control.

The Nissan GT-R is a high-performance Japanese sports car known for its all-wheel-drive traction and strong twin-turbo performance. In this segment, it’s used as a camera platform for filming high-speed chase and circuit footage, with cameras mounted to capture dramatic motion.

A tracking rig is a camera-mounting setup used to keep a vehicle’s motion smooth and consistent in the frame. In this context, the “GTR Godzilla tracking rig” turns the Nissan GT-R into a moving platform for filming high-speed chase sequences.

The Rolls-Royce Ghost is a luxury sedan from Rolls-Royce, built around a quiet, comfortable ride and a powerful V12 (in most Ghost generations). In this segment, it’s mentioned as the car the host drove on a long trip with the same person who does high-speed filming work.
